To all whom t may concern,

Be it known that l, JOHANN Sonnnr'rn, engineer, citizen of the German Republic, residing at Zeesen-Koenigs-lVustei-hausen, near Berlin,Ger1nany, have invented certain new and useful Improvements in irships (for which l tiled an application for patent in Germany September 12th, 1913, patent allowed underyNo. 301,647), of which the following is 'a specification.

The present invention relates to improvements in ties for air-ships with a rigid frame work, according to which the said ties transect the body of the air-shipsv and stay the framework, thereby at the same time reducing the strain on the cover thereof or the envelope ofthe framework. With the heretofore known tie-arrangements the ties are so disposed as to act in the vertical plane, that is at right angles to the longitudinal axis of the air-ship. f, in such an air-ship one of lthe gasfihambers, Awhich are disposed side by side should become empty in consequence of a defect in ghe envelope, or should even not be filled to Ahe same degree as the other chambers,considerable side pressures will ensue, which will act on the transverse ties of the frame work, disposed between the gas cells. By these side pressures acting upon them, the said transverse ties are subjected to very severe stresses, whereby the thrust is transferred to the frame work itployed in an airship with transverse frame rings tied by wires. Figs. l, 2, and 3 show an arrangement for a frame work with radial tie Wires meeting at a central cross ing point in the longitudinal while Fig. -L shows a modification, according to which the tie wires of the frame rings cross each other at several points.

ln both modifications the crossing points of the tie wires s of the frame rings are Specification of Letters Patent.

coupled by tractive members c which are carried through the different gas cells.

In the arrangement according to Figs. 1, 2, and 3, in which thevtransverse tie wires a; meet in a central point in the longitudinal axis7 there is provided only one such longi- 'tudinal tie Wire c extending along the said longitudinal axis of the airship, Whereas in the arrangement according to F ig. 4 the four crossing points t1, t2, t3, t4, `have been chosen as coupling points for the tie wires, so that here we have four longitudinal ties c.

In order that the envelope of the gas cells may be relieved of all strain, the gas cells are provided with indentures al at the center of the end wall at the place Where the longitudinal ties are attached, the indentations being preferably conical. At the crossing points of the transverse tie wires s preferablyspecial coupling members, such as the eye-plate e shown in 3, are employed. The longitudinal ties are passed through the gas cells either by means of the angles and eyes disclosed in my prior Patent No. 992- 909 grantedltlay 23, 1911, or by aid of further eye-plates It, which are riveted to each other through the material (1I of the cells and short intermediate tie members c1 coupling said plates it to the plates e (Fig. 3). The arrangement may, also, be such thatthe ties may be held taut while the gas cells are being inflated; in this case a pulley block, to be operated from below is substituted for the short intermediate ties.

TWhat I claim is:

1. In an airship the combination, with a rigid frame work, gas cells and transverse ties, of longitudinal ties, coupled both to the end walls ot' the gas cells and.to the transverse ties of the frame work.

2. In an airship, the combination with a rigid frame-work and transverse frame rings, of crossed transverse tie wires by means of which the said frame rings are stayed7 longitudinal ties coupled with the transverse tie wires at points where the transverse wires intersect. and gas cells with indented walls. said lmigitudinal ties being attached to the indented walls of the said gas cells.
